Net neutrality is a topic I wrote about frequently some years ago. If required, net neutrality would be a policy required by the FCC that ISPs (Internet Service Providers) would have to carry all content at the same speed. The original concern was that ISPs might prioritize their own content (a common situation would be a cable service that provides Internet and cable who might prioritize their own subscription video over video such as YouTube content) or offer a special speed priority for content providers who would pay the ISPs for such service. The concept was that the companies that carry content to consumers would function as common carriers.
Movement on the provision was stopped during the Trump administration and when Biden was elected his nomination to the FCC was blocked. The FCC decisions are made by a 5 person committee with 2 individuals affiliated with each party and the fifth by the party in power. A new individual has just been and the now Democratic-controlled committee is again intended to move on net neutrality.
While it is true that ISPs did not ever take advantage of their opportunity to take advantage of their freedom, it is argued to be a positive development for consumers that the Internet would be run as a common carrier.
